Brief Description 

    

PSW.BugBear is a keylogger type Trojan. It is dropped into the affected computer by a worm called Bugbear.

The aim of PSW.BugBear is to log the computer keystrokes and saves them in a file on the hard disk of the affected computer. By doing this, it can include valuable information in the file, such as the user name and password for logging on to the computer, credit card numbers, etc. Once this information has been saved in the file, PSW.BugBear sends it to certain e-mail addresses, which are encryted in its code.

Visible Symptoms 

    

PSW.BugBear is difficult to recognize, as it does not display any messages or warnings that indicate it has reached a computer.
